Butterfly needles come in several gauges - 21, 23, and 25-gauge.
Butterfly needles
Safety needles will be 22g or less. Butterfly needles will be 21g or less.
Yes, a 30 gauge needle is larger than a 31 gauge needle. In the gauge system, a higher number indicates a smaller diameter, so a 31 gauge needle is thinner than a 30 gauge needle. Therefore, the 31 gauge needle would be the smaller of the two.
A 25-gauge needle is smaller in diameter than a 23-gauge needle. The larger the gauge number, the thinner the needle, so a 25-gauge needle has a smaller lumen compared to a 23-gauge needle. This means that for tasks requiring finer needles, such as pediatric or cosmetic procedures, a 25-gauge needle would be preferred.
Depends how it is drawn- Butterfly or straight stick 19 g and 21 G are the normal straight stick. If you use a buterfly to draw the lab then they are ususally 21 or 23 Gauge. (Remember the bigger the gauge number the smaller the needle width). The smaller the needle width the higher the chance of hemolization (cell squishing)
The 21 gauge is a smaller needle.
Gauge is the term that indicates the diameter of the needle. Most commonly the needles that are used for medical purposed range from 7 Gauge to 33 Gauge, according to the Stubs scale. 7 Gauge needle will have the largest diameter while as the number increase, the diameter decreases. Therefore the 33 Gauge needle has the smallest diameter. So a 26 Gauge needle will have a smaller diameter than that of the 18 Gauge needle.

Yes, the larger the gauge the smaller the needle size.
The gauge of a needle is determined by its diameter, with smaller gauge numbers indicating larger needle diameters. Thicker medications or fluids may require a larger gauge needle for administration, while thinner medications may be better suited for smaller gauge needles to minimize discomfort for the patient.
Which of the following needles has the widest lumen?
Yes, a 30 gauge needle would be tiny, while an 8 guage needle is huge.
